2-2

The settings for the test equipment shown in Figure 2–1 are described below:

-

Function generator is set to output a 5.5-V square wave with rise and fall
times of 2 ms, top width of 5 ms, and a period of 1 ms.

-

Power amplifier is set to a gain of 1 dB and a minimum slew rate of 2500
V/

µ

s.

-

Power supply capable of 

±

10-V swing and a 0.5-A current limit to power

the power amplifier.

-

A four-channel oscilloscope with channel one’s voltage probe connected
to J1 (IN), channel two’s voltage probe connected to J3 (OUT), and
channel three’s voltage probe connected to J4 (PG). Connect channel
four’s current probe around the output load resistance. Set the scope to
trigger off of channel one so that one full waveform is displayed on the
screen.

-

A 330-

Ω

 resistance for 10-mA of output current (or 10-mA electronic load)

connected between J3 (OUT) and J2 (GND).

After powering on the amplifier, the input voltage, output voltage, and output
current is displayed.
